I [u][b][i]suspect[/i][/b][/u] (but do not know) that eventually, we would have the ability to "share" our linked ID's (to Facebook, Google+, etc.) to others. But I would also imagine that the privacy issues and user controls over that linking and display of those links would have to be VERY carefully controlled. But, in theory, we could then "share out" links to our FB page, our Twitter, YouTube, or other sites/profiles across the web. This would have the advantage (and the risk) of making our accounts here even more "the real me" and more valuable.
